Title: Manufacture of dyestuffs
IPC: C09B19/00
Filed: 1930-07-19
Abstract: Gallocyanines; printing.-Simple gallocyanines derived from meta-substituted alkylaniline, and having the general constitution defined in the parent Specification, are converted into derivatives, which still retain the meta-substituent, by condensation with an aromatic hydroxy compound.  The latter may contain sulphonic groups, or the products may be sulphonated, either in the lenco form or in the oxidized form, to render them soluble in water.  The products, like those of the parent Specification, show greater resistance to reducing agents as compared with the corresponding dyes unsubstituted in the meta-position (see Specifications 24802/93, 15064/94, 16301/95, [all in Class 2, Acids and salts, Organic &c.], and 6272/09, [Class 2 (iii), Dyes &c.]), and are suitable for use in discharge printing.  In examples, (1) the simple gallocyanines from nitrosodimethyl- or -diethyl-m-toluidine and gallomide are condensed with resorcin or with another aromatic hydroxy compound, such as b -resorcylic acid, pyrogallol or gallic acid, in the presence of hydrochloric acid; the products may be sulphonated by treating their dry-leaved compounds with sulphuric acid, and (2) the gallocyanine from nitrosodimethyl-m-toluidine and gallic acid is condensed with 2-naphthol-6-sulphonic acid in the presence of caustic soda or of an acid; other naphthol-sulphonic acids or aromatic oxycompounds may be used.

Title: Improvements in or relating to hydraulic rams
IPC: F02D9/00
Filed: 1943-12-31
Abstract: 573,713. Hydraulic machines. COLLEY, R. H. Dec. 31, 1943, No. 21938. [Classes 69 (ii) and 135] The supply of liquid to alternative ends of the cylinder of a ram 10, which may operate the change-speed gear of the supercharger of an internal-combustion engine, is controlled by a valve 19 yieldingly displaced, e.g. by liquid supplied to its ends through valves 33, 34 solenoidally operated, from its neutral position, a lost-motion coupling between ram and valve returning the valve to its neutral position at the end of a stroke, while a centralizing spring 50 returns the valve to its neutral position when not constrained by the ram or the yielding means. The lost-motion coupling comprises a lever 45 freely mounted on a shaft which also freely carries a double arm 51, 52 and a single arm 48 connected to the arm 51 by the spring 50 and having an abutment 49 ; the arms coact with pins respectively on the lever and on a cam 12 actuated by the ram to operate the control. Liquid flows to the valve through a pipe having a lightly-loaded valve 16, and in the neutral position flows away through pipe 23 ; when the valve is moved to an end position, the liquid passes by a pipe 28 or 29 to the ram cylinder and escapes through the other pipe and pipe 23. Pipes 30, 38 also convey liquid from opposite sides of the valve 16 to the solenoidal valves, operation of which determines whether the lower or higher pressure liquid is conveyed to either end of the valve 19. The solenoids may be actuated by hand or automatically, e.g. by aneroid devices, a manual over-riding switch being provided. Specification 572,936 is referred to.

Title: Apparatus for furnishing electrical signals for torque measurement
IPC: G01L3/10
Filed: 1961-06-16
Abstract: 910,950. Measuring electrically. MESSINJASCHIN, G. A. June 16, 1961 [June 16, 1960], No. 21949/61. Class 40 (1). Apparatus for electrically measuring the torque on a shaft includes means for mechanically magnifying relative movement between two parts of the shaft which means include first and second wheels coaxial with and spaced apart on the shaft, a third wheel coupled to the first two wheels and coaxial with the shaft, so that relative turning between the first and second wheels causes proportionally greater turning between the second and third wheels, the wheels being toothed so as to cause generation of A.C. in an adjacent stator when the shaft turns. Hollow shaft 11 has secured to it two wheels 13, 15, there being a third wheel 14 mounted for rotation on, and coaxial with, wheel 13. Wheels 13, 15 are mounted on the shaft by rings of wire 12 clamped to the wheels so as to accurately define a relatively short measuring length L. Wheels 14, 15 have toothed rims of equal tooth-pitch, and co-operate with pick-up heads 17, 18 so that rotation of the wheels produces alternating currents in the pick-up heads. A rockable ring 24 surrounds the shaft and is pivotally mounted on wheel 13 by pin 23. A pin 25 mounted on ring 24 extends into a recess 26 on wheel 15, and a pin 28 on wheel 14 extends into a recess 27 in wheel 15, diametrically opposite pin 25. When a torque is exerted on the shaft the relative movement between wheels 13 and 15 is magnified by ring 24 and transmitted to wheel 14. The relative displacement between wheels 14 and 15 produces a relative change of phase between the outputs from the pick-up heads. The phase change may be measured by applying each output to an amplitude limiter, differentiating the resulting rectangular pulses, and combining the two differentiated outputs by applying them to a bi-stable multivibrator, whereby rectangular pulses are obtained, the width of the pulses being a measure of the phase difference between the original signals. These pulses may be amplified and applied to a measuring instrument. The amplifiers and multivibrator are preferably transistorized. Zero-point calibration may be achieved by removing pin 22, which normally secures the stator against rotation, and rotating it about the stationary rotor.

Title: On-the-fly printer
IPC: B41J9/10
Filed: 1969-04-30
Abstract: 1,240,604. Selective printing. SUWA SEIKOSHA K.K. 30 April, 1969 [30 April, 1968 (2); 13 May, 1968 (3)], No. 21999/69. Heading B6F. [Also in Division H2] A high-speed printer includes a hammer 1 mounted on a lever 2 which is actuated through a trigger lever 14 selectively strikable by a tooth 11 on a wheel 10. The hammer 1 cooperates with a continuously rotated print drum 4, the drum 4 and wheel 10 being synchronized such that the tooth 11 is in operative position for each character on the print drum 4. The wheel 10 may have a plurality of teeth. The trigger lever 14 is actuated by an electromagnet 26 and armature 25, which rotates the trigger lever 14 about a pin 18 so that its end 34 is in the path of the tooth 11. Repeat action is prevented firstly by provision of a projection 16 on the lever 14 which engages a stop 17 and initiates return of the lever 14 to rest position before the hammer 1 strikes the print drum, and secondly by making the cycle of action of the trigger lever take slightly longer than one rotation of the tooth 11. Line-spacing.-A roller 53 feeds paper between the hammer 1 and drum 4. The roller 53 is driven by a pawl (106, Fig. 5) reciprocated by an electromagnet (105) for each complete revolution of the print drum 4, sensed by a magnetic pulse generator rotated with the drum.

Abstract: 598,002. Torque rods. JAGUAR CARS, Ltd., and HEYNES, W. M. Aug. 28, 1945, No. 22052. [Class 79 (iv)] [Also in Group XXXII] A road vehicle suspension comprises a through axle casing 15 for a pair of driving wheels each end of which is shackled below the axle to a transverse arm 13 fast on a longitudinally extending axially-located shaft 22 journalled about its axis at spaced points 23, 24 with respect to the chassis frame, resilient means opposing movements of the arms 13 due to the load. As shown the shafts 22 are of tubular form and the resilient means comprise torsion rods 33 each being rigidly secured at one end to the respective arm 13 and being in splined engagement with a portion of the chassis frame at the other end 35. Each shaft 22 is carried by plain and thrust roller bearings 23, 24 respectively. Shackles 12 connecting the arms 13 to the axle casing are of H-section, the limbs of which are widely spaced laterally to avoid excessive torsional stressing of the casing, and have rubber bush type pivotal connections. A strut type shock absorber may be mounted between each arm 13 and the chassis frame above and in an alternative construction a strut type compression member, coiled spring or compressed gas unit may be mounted in this position to constitute the resilient means in lieu of the torsion rods 33. The shafts 22 are normally mounted horizontally in order to absorb driving and braking torque but they may be inclined slightly upwardly to counteract the effect of pitching movement on acceleration and braking. Transverse sway is controlled by a laterally disposed link pivotally mounted at its ends to the axle casing and chassis frame respectively.

Filed: 1948-08-21
Abstract: 664,372. Pneumatic tyres. CABALLERO, R. L. June 24, 1949 [Aug. 21, 1948], No. 22118/48. Class 144 (ii). In a replaceable-tread tyre, an inextensible tread band A has a relief pattern on its inner periphery to interlock with a conforming relief pattern formed on a tyre cover B, and air channels 9, 22 lead from the junction of the two portions A and B to the outside of the tyre, said air channels 9, 22 being openable to exhaust air entrapped in said junction and subsequently closable to prevent entry of external air and to effect a " suction " action between the two tyre portions. The interlocking relief patterns may be in the form of continuous or broken longitudinal ribs 10 and grooves 11 of half-round, wedge, dove-tail or other section interspaced respectively by grooves and ribs having flat or rounded bases and crests. As shown in Fig. 5, the air channels may be formed either radially in the tread A (channels 22) or transversely in the cover B (channel 9) opening at each side thereof as at 21. In the latter case a valve may be fitted at the opening 21 to facilitate extraction or injection of air as required when fitting or removing the tread A. The tread band A may be of natural or synthetic rubber with a reinforcing insert 4 of fabric or cord layers, or of leather, between heat insulating fabric layers 5, 5<SP>1</SP>. The abutting marginal portions 23 of the tread A and cover B may be flat or curved in crosssection or may have interlocking transverse or oblique ribs and grooves. On assembly these marginal portions may be cemented together with rubber solution or mastic to exclude air and dirt. Fig. 23 shows an arrangement wherein the tread band A is formed of a rigid ring 40 of light metal or heat insulating plastic material, with the relief pattern on its inner periphery and a rubber tread on its outer periphery. To facilitate assembly of the tyre, a flat inextensible band 20, Fig. 8, of metal or fabric is inserted in the cover B so that inflation of the inner tube C, Fig. 9, is restricted to cause pressure on the inner side walls only of the cover B and thus effect a decrease in the overall diameter thereof. The tread band A is then engaged on the cover B, and the tube C deflated to cause expansion of the cover diameter and effect the interlocking of the relief patterns. The band 20 is removed and the tread pressed firmly into position to expel entrapped air through the air channels 9 or 22. The outlets of the air channels are then sealed with small plugs, rubber solution or mastic and may be marked to indicate their position. Fig. 11 shows a combined inextensible fabric band 25 and flat-topped air tube 24 which may be used for assembly and removal operations instead of the separate band 20 and tube C. The Provisional Specification states that to facilitate manipulation during changing of a tread band, the tyre may be mounted on a strong but light wheel of light metal or wood. The tread bands may be made in colours to blend or contrast with that of the tyre.
